Dispositivo de mecanizado por arranque de virutas con anillo portacuchillas para el mecanizado por arranque de virutas de maderas troceadas.Start-up machining device shavings with ring holder for the mechanized by start of chopped wood chips.
La invención se refiere a un dispositivo de mecanizado por arranque de virutas con anillo portacuchillas para el mecanizado por arranque de virutas de maderas troceadas. Un dispositivo de mecanizado por arranque de virutas de este tipo se conoce, por ejemplo, del documento DE3247629C1. El documento EP-A-0807500 da a conocer un dispositivo de mecanizado por arranque de virutas según el preámbulo de la reivindicación 1.The invention relates to a device of machining by chip removal with knife holder ring for the machining by cutting wood chips. A chip starter device of this type is knows, for example, of document DE3247629C1. The document EP-A-0807500 unveils a chip start machining device according to the preamble of claim 1.
Dispositivos de mecanizado por arranque de virutas de este tipo tienen la siguiente construcción: El dispositivo de mecanizado por arranque de virutas comprende un anillo portacuchillas. El anillo portacuchillas, por su parte, tiene una corona de paquetes de cuchillas. Los paquetes de cuchillas están soportados por dos anillos de soporte que encierran los paquetes de cuchillas entre sí. El dispositivo de mecanizado por arranque de virutas con anillo portacuchillas presenta además un rotor con una pluralidad de palas de rotor.Start-up machining devices chips of this type have the following construction: chip start machining device comprises a knife ring The knife ring, meanwhile, It has a crown of blade packs. Blade packs they are supported by two support rings that enclose the blade packs each other. The machining device by chip removal with knife holder ring also features a rotor with a plurality of rotor blades.
Cada paquete de cuchillas contiene los siguientes componentes: una placa de desgaste, situada en la zona del recorrido circular de las palas del rotor, un soporte de cuchilla, una placa de sujeción, así como una cuchilla sujetada entre el soporte de cuchilla y la placa de sujeción. Para la sujeción se usan al menos dos tornillos de fijación que están dispuestos a una distancia mutua en la dirección longitudinal del paquete de cuchillas. En correspondencia con los tornillos de fijación, la placa de sujeción del paquete individual de cuchillas presenta un taladro, la cuchilla presenta una ranura y el soporte de cuchilla, un taladro roscado. El tornillo de fijación pasa a través del taladro de la placa de sujeción y la ranura de la cuchilla y se enrosca en el taladro roscado del soporte de cuchilla.Each pack of blades contains the following components: a wear plate, located in the area of the circular path of the rotor blades, a support of blade, a clamping plate, as well as a blade held between the blade holder and the clamping plate. For the fastening are used at least two fixing screws that are arranged at a mutual distance in the longitudinal direction of the blade pack In correspondence with the screws of fixing, the clamping plate of the individual blade pack it has a drill, the blade has a groove and the support of blade, a threaded drill. The fixing screw passes through of the drill of the clamping plate and the groove of the blade and it Screw into the threaded hole of the blade holder.
Las cuchillas tienen sólo una duración limitada de algunas horas. Después están desgastadas y se tienen que sustituir por nuevas cuchillas. Esto implica la necesidad de desmontar los paquetes de cuchillas. Por tanto, se desenroscan los tornillos de fijación, se extraen las cuchillas desgastadas, se instalan nuevas cuchillas, se coloca la placa de sujeción y se pasan los tornillos de fijación a través de los taladros de la placa de sujeción y las ranuras de las cuchillas, así como se enroscan en los taladros roscados de los soportes de cuchilla. Se trata de mantener la posición exacta de las cuchillas y de las placas de sujeción. Especialmente hay que ajustar con exactitud el resalto de la cuchilla, es decir, la posición radial del filo. Este proceso requiere mucho tiempo, cuidado y atención.The blades have only a limited duration of a few hours Then they are worn and have to Replace with new blades. This implies the need to disassemble the blade packs. Therefore, unscrew the fixing screws, worn blades are removed, new blades are installed, the clamping plate is placed and the fixing screws pass through the holes in the plate clamping and grooves of the blades, as well as screwed into the threaded holes of the blade holders. Is about maintain the exact position of the blades and plates subjection. Especially you have to adjust exactly the highlight of the blade, that is, the radial position of the cutting edge. This process It requires a lot of time, care and attention.
La placa de sujeción se fijaba hasta ahora con ayuda de una ranura guía y un pasador que se ha de engranar en ésta.The clamping plate was fixed so far with help of a guide groove and a pin to be engaged in is.
La invención tiene el objetivo de configurar un dispositivo de mecanizado por arranque de virutas con anillo portacuchillas del tipo descrito al principio de modo que el paquete de cuchillas se pueda montar con facilidad y rapidez, lográndose una posición más exacta de la placa de sujeción y de las cuchillas.The invention aims to configure a chip starter machining device with ring knife holder of the type described at the beginning so that the package of blades can be mounted easily and quickly, achieving a more exact position of the clamping plate and the blades
Este objetivo se consigue mediante las características de la reivindicación 1.This objective is achieved through characteristics of claim 1.
Por consiguiente, el tornillo individual de fijación, junto con el taladro de la placa de sujeción, la ranura de la cuchilla y el taladro del soporte de cuchilla, se usan para el centrado. De este modo se logra una simplificación considerable durante el montaje, así como una gran precisión en el ajuste de la cuchilla en cuestión.Therefore, the individual screw of fixing, together with the hole in the clamping plate, the groove of the blade and the hole of the blade holder, are used for centered. In this way a considerable simplification is achieved during assembly, as well as great precision in adjusting the blade in question.
